Description

The present invention relates to a double-walled wall section for a vehicle body, such as a swap body or semitrailer for trucks, or a large-capacity container, in particular a container, wherein the wall portion has a substantially planar inner side and a substantially planar outer side and a preferably continuous base profile, the Base profile is bent such that it has inner sides directed to the inside and outer sides facing outer sections, the inner sections and the outer sections parallel to each other, and the base profile between the inner sections and the outer sections in the form of folded intermediate sections, wherein each two intermediate sections with an intermediate arranged outer portion defining an inner recess and two intermediate portions with an inner portion disposed therebetween, an outer recess. In addition, a vehicle body, in particular swap body or semitrailer for trucks, or a large-capacity container, in particular containers, proposed with a bottom portion and at least one wall portion.

Corresponding wall sections or profiles are well known in the prior art. For example, the DE 20 2005 005 358 U1 a compound of several profile parts, so that they finally form a continuous wall profile. In this case, each profile part has a middle part and two opposite edge regions, wherein the edge regions are bent several times and adjacent profile parts engage with the edge regions. The connection is characterized in that at least one of the two edge regions encloses an angle of inclination of less than 90 ° with the central part, and the edge regions are furthermore bent in such a way that two adjacent longitudinal profiles are prestressed get stuck together. Although this allows a relatively high stability of the wall to be achieved, the structure and in particular the assembly is quite complex, so that there is room for improvement in this respect.

Furthermore, by the DE 195 27 569 A1 a side wall for vehicles, especially for trough structures, described. The side wall has a wall surface lying inside in the position of use and a wall surface lying outside in the position of use, which is at a distance from the inner wall surface. This is to ensure that while maintaining a high load capacity of the wells, the visual appearance of the outer surface is maintained even when buckling of the inner Muldenbleches to meet in particular the high requirements as a labeling or advertising space. According to the invention, it is proposed that the inner wall surface has a wall-thickness which withstands high loads and the outer wall surface has a significantly smaller wall thickness, wherein profiled sheets holding a gap between the wall surfaces are provided. However, this results in a wall surface with a plurality of overlaps of the respective sheet metal elements, so that the side wall has an increased weight and also requires a high material usage.

It is therefore an object of the invention to provide a wall section and a vehicle body or container with a corresponding wall section, wherein the wall section should be characterized by a high stability in yet easy to be assembled structure.

This object is achieved with respect to the wall portion in that the outer recesses are provided with outer covers which extend between two adjacent intermediate portions and form with the adjacent to these intermediate portions outer portions of the outer side of the wall portion and the inner recesses with inner covers are provided, which extend between two adjacent intermediate portions and form with the adjacent to these intermediate portions inner portions of the inside of the wall portion. This results in a wall section with a beaded base profile, which alternately forms part of the inside and part of the outside. The rest of the inside is formed by the inside covers and the rest of the outside by the outside covers. If one looks at the outside, then outer sections and outer covers alternate in the transverse direction of the wall section. The same applies to the inside, where interior sections and interior covers alternate. The result is a double-walled wall section with two parallel surfaces, namely the outside and the inside described. Due to the bent-off shape of the base profile, a high stability of the wall section is also ensured, with the advantage that the design as a double wall achieves the advantage that damage to the outer wall does not necessarily lead to deformation of the inner wall and vice versa.

It is particularly advantageous if the inner covers and / or outer covers are connected to adjacent intermediate sections. Although it is also possible that the inner and outer covers are flat and only communicate with the adjacent inner and outer sections. However, if the covers mentioned are folded according to the fact that the folded sections can be connected to the intermediate sections, the stability is significantly increased. Also, the covers can be connected via the intermediate sections directly to the base profile, so that the respective outer and / or inner side of the wall portion can be configured as flat as possible.

It is also advantageous if the inner covers and / or outer covers are connected to the base profile by welding, gluing and / or by means of screw or rivet joints. Such compounds ensure a secure fit, in particular the latter Connections allow replacement of the respective inner and outer covers.

Likewise, there are advantages when the inner covers are connected to the base profile by welding and the outer covers to the base profile by means of screw or rivet connections. In particular, in the area of the inside of the wall section increased stability is required, since this page can come into contact with the corresponding cargo or forklift tines after installation in a vehicle body or container. If the inner cover welded to the base profile, so there is a durable connection, which in particular also prevents damage to the inside of a buckling of the outside of the wall section result. On the other hand, it is advantageous if the outside is configured as flat as possible in order to be able to attach advertising messages, company logos or other decorations to it. Therefore, for attaching the outer covers offer connection solutions that are not visible from the outside. If the outer covers, as already described, folded and are in contact with the not visible from the outside intermediate portions and / or inner portions, then this contact can be used to connect both elements in this area, for example by means of rivets or screws, which also are easily detachable again. In this way, in case of damage to the outer covers an easy replacement of the same possible.

It is also advantageous if between the inner covers and the base profile and / or between the outer covers and the base profile a sealant, such as polyurethane, is arranged. As a result, the entry of liquid into the wall section or into the interior of a vehicle body or container equipped therewith is prevented in a simple manner. The sealant may be applied punctiform or flat and the entire contact surface between the Covers covers and the base profile or just a few sections thereof.

Advantageously, the intermediate sections are substantially perpendicular to the inner sections and / or the outer sections and define their distance from each other by their geometry. This results in a particularly high stability of the wall section, in particular in a direction perpendicular to the outside or inside. The basic profile is bent in this case in the transition areas between the outer portion and intermediate portion or between inner portion and intermediate portion by 90 °.

In a further advantageous embodiment of the invention, the intermediate sections extend in an acute or obtuse angle with respect to the inner sections or the outer sections and also define their distance from each other. Such a configuration ultimately results in trapezoidal inner and outer recesses, so that the stability is increased in particular parallel to the inner and outer surfaces. Also, vertical and sharp or blunt transitions are possible in any change.

Moreover, it is particularly advantageous if the inner covers and / or outer covers have a substantially rectangular, U-shaped or C-shaped cross-section. While a rectangular and a C-shaped cross section allow attachment of the covers over the parallel sections of the base profile, U-shaped covers are preferably connected to the intermediate sections. Likewise, of course, other cross sections, for example in the form of an omega, conceivable. Likewise, the Abkantungsbereiche can be rounded or sharp-edged. In principle, all profiles can be used, which allow an outer or inner cover of the outer and inner recesses.

Particular advantages arise when the inner covers have a substantially U-shaped cross-section and the outer covers have a substantially C-shaped cross-section. As already described, it is necessary on the inside to ensure a stable connection between the base profile and the inner cover. Such a connection is obtained, for example, in a U-shaped cross section by welding the respective end portions of the U-shape with the intermediate portions. By contrast, the result of a C-shaped cross-section is the possibility of connecting the outer cover with the respective parallel inner sections, so that a particularly flat outer side of the wall section results without visible connecting elements.

It is also extremely advantageous if the inner sections and / or the inner covers have fastening elements, in particular in the form of apertures. These allow after installation of the wall section in a vehicle body or container securing the cargo. The fasteners can be designed for this purpose as eyelets, hooks, holes or other bulges. Also in this context, a welded joint between the inner cover and the base profile is recommended in order to ensure a secure hold of the load.

Likewise, it may be of great advantage if the base profile consists of individual elements which are connected to each other at contact points, in particular welded or glued. As a result, especially the production of the basic profile is simplified, which may be well over 20 meters depending on the length of the desired wall profile.

The vehicle structure according to the invention, in particular in the form of a swap body or a semitrailer for trucks, or the large-capacity container according to the invention, in particular in the form of a container, finally characterized by the fact that the wall portion is formed according to one or more aspects of the previous description, wherein In this case, the advantages mentioned remain even after installation of the wall section.

FIG. 5

a front view of the inside of a vehicle body according to the invention.

FIG. 1 shows a plan view of a base section 1 of a wall portion 2 according to the invention, which extends perpendicular to the plane, wherein the base profile 1 and this having wall portion 2 an inner side 3, which shows after installation in a corresponding vehicle body or container inwards, and an outer side 4, correspondingly facing outwards.

The base profile 1 is formed beaded, ie it has the inside 3 directed inner sections 5 and directed to the outside 4 outer sections 6. Between the inner sections 5 and the outer sections 6, the basic profile 1 finally extends in the form of bent intermediate sections 7.

As a result of this bending, internal recesses 8 are formed which are formed by two adjacent intermediate sections 7 and the outer sections 6 arranged therebetween. Analog arise outer recesses 9, which are limited according to two adjacent intermediate sections 7 and the interposed inner sections 5.

At this point it should be noted that FIG. 1 only shows a section of a basic profile 1, wherein its course is characterized by the alternating sequence of the inner recesses 8 and outer recesses 9 shown. At the respective ends of the basic profiles 1 finally connecting elements for connection with further wall sections 2 or corresponding end elements can be arranged.

The essence of the invention is, for example FIG. 2 refer to. Thus, the outer recesses 9 are provided with outer covers 10 which extend between two adjacent intermediate sections 7 and form the outer side 4 of the wall section 2 with the outer sections 6 adjoining these intermediate sections 7. Likewise, the inner recesses 8 are provided with inner covers 11 which extend between two adjacent intermediate sections 7 and form the inner side 3 of the wall section 2 with the inner sections 5 adjoining these intermediate sections 7. The result is a double-walled wall section 2 with a flat inner side 3 and a flat outer side 4, which can be provided in a simple manner with advertising or other inscriptions. The wall section 2 also receives a high stability through the beaded base profile 1, which ensures a long service life of the wall section 2. The arrangement of the inner covers 11 and the outer covers 10 finally leads to a double-wall section 2, in which less damage to the inner side 3 does not directly lead to a deformation of the outer side 4 and vice versa.

The design of the inner covers 11 and the outer covers 10 can the synopsis of Figures 2 and 3 , which is an enlarged view of the section A in FIG. 2 represents, be removed. As can be seen, the inner covers 11 and the outer covers 10 have different cross sections. In addition, the respective fasteners of different design. Thus, the inner covers 11 are glued or welded to the adjacent intermediate sections 7 and have a U-shaped cross-section. In this way, a connection between inner cover 11 and base profile 1, which is characterized by a high strength, so that the risk of deformation can be minimized by unsecured load or forklift tines. In contrast, the outer covers 10 have a C-shaped cross-section. As a result, the outer covers 10 can be connected to the inner sections 5 from the inside with the aid of, for example, rivet connections 12. As a result, the outer side 4 of the wall section 2 by the internal attachment of the outer covers 10 on a particularly flawless surface, which is particularly suitable for printing. Of course, the inner covers 11 and the outer covers 10 may also have the same cross-section or be connected in the same way with the basic profile 1. Also, the outer covers 10 may be welded or glued and the inner covers 11 releasably secured, for example by means of riveted joints 12.

FIG. 3 can also be seen that between the outer covers 10 and the intermediate portions 7 and the inner portions 5 of the base section 1, a sealant 13 may be arranged to prevent ingress of moisture into the later vehicle body or container.

Furthermore, it can be seen from the cited figures that the intermediate sections 7 are substantially perpendicular to the inner sections 5 and / or run the outer sections 6 and thus define their distance from each other.

Alternatively, however, the intermediate sections 7 can also run at an acute or obtuse angle with respect to the inner sections 5 or the outer sections 6. The latter alternative is in FIG. 4 shown, wherein the inner covers 11 and outer covers 10 have adapted to the transition angle trapezoidal cross-section. Again, the distance between the parallel inner sections 5 and outer sections 6 is determined essentially by the length of the intermediate sections 7 (relative to the plane of the page).

In addition, shows FIG. 4 in that the base profile 1 can consist of several individual elements which are connected to one another, for example welded, at corresponding contact points 18. In this case, the respective individual elements can be connected overlapping each other (see FIG. 4 : left contact point 18). Likewise, the connection can be made by butt welds, as in FIG. 4 the example of the right pad 18 is shown. It should also be mentioned that the individual elements can have any length. Thus, a single element may comprise only a short section of the base profile 1. Likewise, however, it is also possible that a single element spans a plurality of the inner sections 5 or outer sections 6.

Finally, in FIG. 5 an inventive vehicle body with a lying in the plane of the wall portion 2, wherein alternately the inner portions 5 and the interposed inner covers 11 can be seen, which in turn form the inside 3 of the wall portion 2 with the inner sections.

Adjacent to the central wall portion 2 extends perpendicular to the plane another wall section 2, which closes the vehicle body to the left. On the right side, another wall 19 is shown, which may be formed as a door unit or may have a corresponding door unit. Of course, this wall 19 may also be formed in the form of a wall portion 2 of the invention and optionally have corresponding charge openings. Furthermore, the vehicle body has a bottom portion 14 and a ceiling portion 15, which are connected in a known manner with the wall sections 2.

Furthermore, the inner sections 5 and / or the inner covers 11 fastening elements in the form of differently shaped openings 16 in order to attach appropriate cargo on the inside 3 can. Likewise, the inner sections 5 and / or the inner covers 11 can be panels 17, e.g. in the form of wood paneling to provide additional protection against damage to the interior wall. In this context, it should be mentioned that the arrangement and selection of the fasteners or any wainscoting depends on the intended use of the vehicle body and also only one type or any combination of said elements can be present. Also, said elements may be provided only on some of the inner covers 11 and / or inner sections 5.

Of course, analogously to the preceding embodiments, the wall section 2 according to the invention can also be used as a wall section 2 for a container.

Incidentally, the invention is not limited to the illustrated embodiments. Rather, all combinations of the individual features described, as shown or described in the claims, the description and the figures and as far as a corresponding combination is technically possible or seems reasonable, the subject of the invention.
